What does it do?

Our application provides email authentication to increase the deliverability and security of your email campaigns. This article explains what authentication is, why it's a good idea to use it, and how it can be set up.

Because of the way email was originally built it's very easy to forge, meaning an email sender might not be who they say they are. An example of this is an email message claiming to be from your bank, when it's actually a scam aimed at stealing money or spreading malicious software.

How does it work?

Authentication technology prevents this from happening by giving ISPs a record of identification to check, to ensure the sender is legitimate. Emails that fail to pass authentication checks may be blocked or put through additional filters, potentially preventing them from reaching the inbox.

ISPs like AOL, Gmail or Yahoo! (as well as corporate email servers) use one or more of these authentication methods to verify sender identity:

Imagine a phishing email being sent from your company because someone had forged your information. Angry recipients and spam complaints resulting from it become your mess to clean up, in order to repair your reputation.

Many ISPs use authentication, among other things, to track sender reputation. Without it, the chances of your emails being filtered are much higher.

How can you set up email authentication and use it in our application !

For both DKIM and SPF setup, you'll need to have access to your DNS records for your domain, and a bit of technical knowledge, you can set up your own authentication records*.

This option is for advanced users because it can be a bit tricky to get working, given the variety of DNS management systems out there. Learn more about this in our guide to setting up email authentication yourself.

*This is the best option for building and maintaining a good sender reputation. By handling authentication through your domain, it means you have control over all emails that affect deliverability for your domain.
